Hess Perlite mines, expands, and processes frothy white perlite for industrial use in a wide range of applications—including horticultural, insulative, filtration, lightweight concrete, fireproofing, and agricultural applications. We also ship perlite ore to other expanders.
The Hess Perlite mine is located in Southeastern Idaho approximately 27 miles Northwest of the expansion plant in Malad. Although the mine has been in operation since 1965, there are still over 10 million tons of perlite reserves remaining, all on patented ground.
Hess Perlite produces the standard perlite grades but will gladly process perlite to any spec you require.
